  2. Radar horizon - Wikipedia

    en.wikipedia.org/wiki/Radar_horizon

    The radar horizon with an antenna height of 75 feet (23 m) over the ocean is 10-mile (16 km). However, since the pressure and water vapor content of the atmosphere varies with height, the path used by the radar beam is refracted by the change in density. With a standard atmosphere, electromagnetic waves are generally bent or refracted downward.

    MADRE over-the-horizon radar at the NRL's Chesapeake Bay Detachment U.S. Navy Relocatable Over-the-Horizon Radar station. The most common type of OTH radar, OTH-B (backscatter), [3] uses skywave or "skip" propagation, in which shortwave radio waves are refracted off an ionized layer in the atmosphere, the ionosphere, and return to Earth some distance away.

  5. Plan position indicator - Wikipedia

    en.wikipedia.org/wiki/Plan_position_indicator

    A plan position indicator (PPI) is a type of radar display that represents the radar antenna in the center of the display, with the distance from it and height above ground drawn as concentric circles. As the radar antenna rotates, a radial trace on the PPI sweeps in unison with it about the center point. It is the most common type of radar ...

    It is coupled with link 16, electro-optics/infrared, radar, GPS, Tactical Data Information Exchange System TADIX-B and Officer in Tactical Command Information Exchange System information to provide a coherent tactical picture for the user.

  7. Atmospheric duct - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_duct

    In over-the-horizon radar, ducting causes part of the radiated and target-reflection energy of a radar system to be guided over distances far greater than the normal radar range. It also causes long-distance propagation of radio signals in bands that would normally be limited to line of sight.

  8. AN/FPS-6 Radar - Wikipedia

    en.wikipedia.org/wiki/AN/FPS-6_Radar

    The AN/FPS-6 Radar was a long-range height finding radar used by the United States Air Force's Air Defense Command. The AN/FPS-6 radar was introduced into service in the late 1950s and served as the principal height-finder radar for the United States for several decades thereafter. It was also used by the Royal Air Force alongside their AMES ...

  9. Duga radar - Wikipedia

    en.wikipedia.org/wiki/Duga_radar

    An over-the-horizon radar sited in the USSR would help solve this problem, and work on such a system for this associated role started in the late 1960s. The first experimental system, Duga, was built outside Mykolaiv in Ukraine , successfully detecting rocket launches from Baikonur Cosmodrome at 2,500 kilometres (1,600 mi).
